although it's a very hard thing to accept, first thing I'm going to do is to assess myself as why does my wife cheated on me. I might ask myself: 'am I not a loving husband to her?' or perhaps, 'isn't she happy being with me?'..... I'm just pointing out that if I'm the main reason, or the problem arose from me, I will find a way to fix it and save our marriage.... of course, I'm going to be disappointed but I can always forgive because of love. :)

Here are some options: 1. If she ends the affair, you forgive her and stay with her. If you choose this option, you must NEVER bring it up again later, or your marriage will suffer greatly. 2. If she ends the affair, you forgive her in your heart, but you do not stay with her because your trust is broken. 3. If she ends the affair, you decide you cannot forgive her and you do not stay with her. This is a bad option because the only person it will hurt over time ... is you. A bitter spirit is worse than the feeling of betrayal. 4. If she will not end the affair, then this is very difficult indeed. You must decide if you will wait and hope she returns -- or if you will move on and not pursue it further. If there are children involved, this is even more difficult. EITHER WAY -- if you wait or if you end the marriage -- try not to let a bitter spirit set in. It will rob your life of enjoyment in every area, and may rob you of a second chance at love, which may come along. My best to you in this difficult decision.
